PCjs Machines

PCjs is a JavaScript-based emulator that allows users to experience classic computers and software from the 1970s-1990s directly in their web browser, including IBM PC compatibles, minicomputers, calculators, and arcade games. The project preserves vintage hardware and software through interactive emulations of machines and programs like the Apple II, early Microsoft Windows versions, VisiCalc, Lotus 1-2-3, and classic games like Space Invaders and Wolfenstein 3D. PCjs is an open-source preservation effort maintained on GitHub that offers users access to period-appropriate public domain software, shareware, and documentation alongside the emulated systems.
